Friday's shooting happened around 2:30 p.m. at 1434 Thomason Avenue, an address well-known to law enforcement. When they arrived on the scene, the teen was dead on the back porch of the home. A weapon was found next to his body, said Tarrant Police Chief Dennis Reno.

Jelks told police the teen was trying to rob him at gunpoint and that's when he fired on him through the closed back door. The weapon police say was used by Jelks in Friday's fatal shooting was on the front porch, marked as evidence while police investigated.

Reno said Woodfin arrived at the scene in a Jeep reported stolen out of Mountain Brook, and said the keys to the stolen Jeep were still in Woodfin's pocket. That jeep had been stolen on Thursday.

Shortly before his death, Woodfin posted a Facebook Live video in which he was brandishing a firearm. Investigators say that video was determined to have been filmed inside Jelks' house, and was among evidence they considered when seeking charges.

The shooting happened, police said, during a dispute between Woodfin and Jelks over guns and a stolen vehicle, but said there was no robbery happening at the time. Jelks remained in Tarrant police custody over the weekend pending the investigation. Detectives were back out at Jelks' home Sunday afternoon after a new piece of potential evidence was found next door to the house where the shooting happened.

Reno said Tarrant officers have been called to the home where Friday's shooting happened multiple times on reports of gunfire, and pointed out old bullet holes in the siding from previous incidents. In fact, he said, they just recently sent a letter of abatement to the owner of the home because of all of the problems police have experienced there.

Court records show Jelks is currently awaiting trial in a 2015 arrest by Vestavia Hills police. In that case, authorities say Jelks the previous year had illegally sold heroin, and did so within three miles of a school or public housing community. They charged him with two counts of unlawful distribution of a controlled substance. Jelks' lawyer last month withdrew from the case, records show.

Jelks was arrested in 2012 on first-degree robbery charges, but that case was dismissed. He was arrested earlier this year by Tarrant police - in January - on a charge of trafficking morphine while in possession of a firearm but that case was dismissed in May 2017.

Jelks was transferred to the Jefferson County Jail just before 8 p.m. Sunday. He is being held on the $250,000 bond.

Randall Woodfin has not public discussed his nephew's killing except for in a prepared statement he released Saturday which read: "My heart is heavy with the loss of my nephew Ralph Woodfin, III," Woodfin said in a prepared statement sent to AL.com on Saturday. "My family would greatly appreciate your thoughts and prayers, and respectfully ask for privacy during this difficult time."
